a17975992c selftests: openvswitch: fix tcpdump execution
Fix the way tcpdump is executed by:
- Using the right variable for the namespace. Currently the use of the
  empty "ns" makes the command fail.
- Waiting until it starts to capture to ensure the interesting traffic
  is caught on slow systems.
- Using line-buffered output to ensure logs are available when the test
  is paused with "-p". Otherwise the last chunk of data might only be
  written when tcpdump is killed.

1234810b16 selftests: net-drv: queues: sanity check netlink dumps
This test already catches a netlink bug fixed by this series,
but only when running on HW with many queues. Make sure the
netdevsim instance created has a lot of queues, and constrain
the size of the recv_buffer used by netlink.

While at it test both rx and tx queues.

0518863407 selftests: net: support setting recv_size in YNL
recv_size parameter allows constraining the buffer size for dumps.
It's useful in testing kernel handling of dump continuation,
IOW testing dumps which span multiple skbs.

Let the tests set this parameter when initializing the YNL family.
Keep the normal default, we don't want tests to unintentionally
behave very differently than normal code.

663ad7481f tools/net/ynl: fix sub-message key lookup for nested attributes
Use the correct attribute space for sub-message key lookup in nested
attributes when adding attributes. This fixes rt_link where the "kind"
key and "data" sub-message are nested attributes in "linkinfo".

For example:

./tools/net/ynl/cli.py \
    --create \
    --spec Documentation/netlink/specs/rt_link.yaml \
    --do newlink \
    --json '{"link": 99,

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Fix bogus test reports in rpath.sh selftest by adding permanent
   neighbor entries, from Phil Sutter.

2) Lockdep reports possible ABBA deadlock in xt_IDLETIMER, fix it by
   removing sysfs out of the mutex section, also from Phil Sutter.

3) It is illegal to release basechain via RCU callback, for several
   reasons. Keep it simple and safe by calling synchronize_rcu() instead.
   This is a partially reverting a botched recent attempt of me to fix
   this basechain release path on netdevice removal.
   From Florian Westphal.

On some systems, neighbor discoveries from ns1 for fec0:42::1 (i.e., the
martian trap address) would happen at the wrong time and cause
false-negative test result.

Problem analysis also discovered that IPv6 martian ping test was broken
in that sent neighbor discoveries, not echo requests were inadvertently
trapped

Avoid the race condition by introducing the neighbors to each other
upfront. Also pin down the firewall rules to matching on echo requests
only.

777f290ab3 selftests/ftrace: adjust offset for kprobe syntax error test
In 'NOFENTRY_ARGS' test case for syntax check, any offset X of
`vfs_read+X` except function entry offset (0) fits the criterion,
even if that offset is not at instruction boundary, as the parser
comes before probing. But with "ENDBR64" instruction on x86, offset
4 is treated as function entry. So, X can't be 4 as well. Thus, 8
was used as offset for the test case. On 64-bit powerpc though, any
offset <= 16 can be considered function entry depending on build
configuration (see arch_kprobe_on_func_entry() for implementation
details). So, use `vfs_read+20` to accommodate that scenario too.

5f2c7ab15f selftests: mlxsw: sharedbuffer: Ensure no extra packets are counted
The test assumes that the packet it is sending is the only packet being
passed to the device.

However, it is not the case and so other packets are filling the buffers
as well. Therefore, the test sometimes fails because it is reading a
maximum occupancy that is larger than expected.

Add egress filters on $h1 and $h2 that will guarantee the above.

cf3515c556 selftests: mlxsw: sharedbuffer: Remove h1 ingress test case
The test is sending only one packet generated with mausezahn from $h1 to
$h2. However, for some reason, it is testing for non-zero maximum occupancy
in both the ingress pool of $h1 and $h2. The former only passes when $h2
happens to send a packet.

Avoid intermittent failures by removing unintentional test case
regarding the ingress pool of $h1.

04d4ce91b0 selftests/bpf: Add more test cases for LPM trie
Add more test cases for LPM trie in test_maps:

1) test_lpm_trie_update_flags
It constructs various use cases for BPF_EXIST and BPF_NOEXIST and check
whether the return value of update operation is expected.

2) test_lpm_trie_update_full_maps
It tests the update operations on a full LPM trie map. Adding new node
will fail and overwriting the value of existed node will succeed.

3) test_lpm_trie_iterate_strs and test_lpm_trie_iterate_ints
There two test cases test whether the iteration through get_next_key is
sorted and expected. These two test cases delete the minimal key after
each iteration and check whether next iteration returns the second
minimal key. The only difference between these two test cases is the
former one saves strings in the LPM trie and the latter saves integers.
Without the fix of get_next_key, these two cases will fail as shown
below:
  test_lpm_trie_iterate_strs(1091):FAIL:iterate #2 got abc exp abS
  test_lpm_trie_iterate_ints(1142):FAIL:iterate #1 got 0x2 exp 0x1

4a475c0a7e selftests/damon: add _damon_sysfs.py to TEST_FILES
When running selftests I encountered the following error message with

 #   File "[...]/damon/./damos_quota.py", line 7, in <module>
 #     import _damon_sysfs

Fix this by adding the _damon_sysfs.py file to TEST_FILES so that it

4ae132c693 selftest: hugetlb_dio: fix test naming
The string logged when a test passes or fails is used by the selftest
framework to identify which test is being reported.  The hugetlb_dio test
not only uses the same strings for every test that is run but it also uses
different strings for test passes and failures which means that test
automation is unable to follow what the test is doing at all.

Pull the existing duplicated logging of the number of free huge pages
before and after the test out of the conditional and replace that and the
logging of the result with a single ksft_print_result() which incorporates
the parameters passed into the test into the output.

7ce1c0921a vsock/test: fix failures due to wrong SO_RCVLOWAT parameter
This happens on 64-bit big-endian machines.
SO_RCVLOWAT requires an int parameter. However, instead of int, the test
uses unsigned long in one place and size_t in another. Both are 8 bytes
long on 64-bit machines. The kernel, having received the 8 bytes, doesn't
test for the exact size of the parameter, it only cares that it's >=
sizeof(int), and casts the 4 lower-addressed bytes to an int, which, on
a big-endian machine, contains 0. 0 doesn't trigger an error, SO_RCVLOWAT
returns with success and the socket stays with the default SO_RCVLOWAT = 1,
which results in vsock_test failures, while vsock_perf doesn't even notice
that it's failed to change it.

adfdd9c685 selftests/bpf: Introduce __caps_unpriv annotation for tests
Add a __caps_unpriv annotation so that tests requiring specific
capabilities while dropping the rest can conveniently specify them
during selftest declaration instead of munging with capabilities at
runtime from the testing binary.

While at it, let us convert test_verifier_mtu to use this new support
instead.

Since we do not want to include linux/capability.h, we only defined the
four main capabilities BPF subsystem deals with in bpf_misc.h for use in
tests. If the user passes a CAP_SYS_NICE or anything else that's not
defined in the header, capability parsing code will return a warning.

Also reject strtol returning 0. CAP_CHOWN = 0 but we'll never need to
use it, and strtol doesn't errno on failed conversion. Fail the test in
such a case.

The original diff for this idea is available at link [0].

subtracting 1 from regno. The same scenario exists for iterator

12659d2861 bpf: Ensure reg is PTR_TO_STACK in process_iter_arg
Currently, KF_ARG_PTR_TO_ITER handling missed checking the reg->type and
ensuring it is PTR_TO_STACK. Instead of enforcing this in the caller of
process_iter_arg, move the check into it instead so that all callers
will gain the check by default. This is similar to process_dynptr_func.

An existing selftest in verifier_bits_iter.c fails due to this change,
but it's because it was passing a NULL pointer into iter_next helper and
getting an error further down the checks, but probably meant to pass an
uninitialized iterator on the stack (as is done in the subsequent test
below it). We will gain coverage for non-PTR_TO_STACK arguments in later
patches hence just change the declaration to zero-ed stack object.

cdd30ebb1b module: Convert symbol namespace to string literal
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

e70140ba0d Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

Snapshots of the graphics sysfs knobs are taken based on file
descriptors. To optimize this process, open the files and cache the file
descriptors during the graphics probe phase. As a result, the previously
cached pathnames become redundant and are removed.

This change aims to streamline the code without altering its functionality.

d071004e62 tools/power turbostat: Consolidate graphics sysfs access
Currently, there is an inconsistency in how graphics sysfs knobs are
accessed: graphics residency sysfs knobs are opened and closed for each
read, while graphics frequency sysfs knobs are opened once and remain
open until turbostat exits. This inconsistency is confusing and adds
unnecessary code complexity.

Consolidate the access method by opening the sysfs files once and
reusing the file pointers for subsequent accesses. This approach
simplifies the code and ensures a consistent method for accessing
graphics sysfs knobs.

1958f4e168 tools/power turbostat: Enhance platform divergence description
In various generations, platforms often share a majority of features,
diverging only in a few specific aspects. The current approach of using
hardcoded values in 'platform_features' structure fails to effectively
represent these divergences.

To improve the description of platform divergence:
1. Each newly introduced 'platform_features' structure must have a base,
   typically derived from the previous generation.
2. Platform feature values should be inherited from the base structure
   rather than being hardcoded.
This approach ensures a more accurate and maintainable representation of
platform-specific features across different generations.

Converts `adl_features` and `lnl_features` to follow this new scheme.
